out.write()空指针异常
这是servlet代码：
public class RequestTest3 extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
String data = "qqq";
request.setAttribute("data", data);
request.getRequestDispatcher("/requestJsp.jsp").forward(request, response);
}
}
这是JSP代码：
<body>
<%
String message = (String)application.getAttribute("data");
out.write(message);
%>
</body>
我把servlet的数据传给JSP，然后输出，运行时出现空指针异常，这是什么回事啊？求各位高手帮帮忙！ Servlet JSP 异常
[解决办法]
为什么要拿application取request域的值？
